The alarm has gone awol . Nothing we can do ti stop it
If we cut the wire to the the thing that makes the screeching noise ...will it have any adverse effects ? Its a GT alarm I am told

No good news for you from me, I'm afraid, Sal. Maybe another bettrr-informed Fruitcake can help?
It needs to be SWITCHED off, I guess, because the sounder (screecher) is self-powered with its own, built-in battery. Cutting wires won't do anything except maybe make it impossible to switch off? I'd reconnect the wires and keep trying to switch it off.
It looks to be Italian-made but I can't find a UK based manufacturer/supplier; I'm left with just Italian suggestions and random UK alarm installers.
Much as it pains me to say it, I think you'll have to take it to an approved installer to get the health of the system checked and find out why you're getting false alarms and why you cannot switch the damned thing off.

Oh, maybe a fresh battery in the alarm fob?? Worth a try for £1.50!

Thanks Boggers
We think its the sounder itself that is the problem. It was making random noises, then full on, then strangled sorts of noises. R put his hand over it and it made a suffocating sort of noise and then stopped ! It hasnt squeaked since so maybe its dead.
If its powered by its own built in battery maybe thats its problem ? Ie battery is dying and hence it shrieks ?
The alarm has never been enabled throughout , so we dont think its a "false" alarm as such. Finding fuse for the alarm system wont help as the alarm is not enabled. We will look and see if the sounder has an on/off. Doubt it as that would be a bit easy. There are 2 wires going into the sounder....tempted to cut them tbh. BUT. , this may have an adverse effect like disabling the engine or something stupid. Everything is Italian as you point out. We cannot find anything in a language that we understand ....

The built in battery is probably an anti tamper system (as in house alarms). That is possibly the fault but you need a meter to check the voltage. The cold weather can drop a battery voltage even more.
Also check every door/window that has alarm contacts fitted (including the bonnet). It might be a bad connection.

Follow those two wires to a connector and try disconnecting it. Either it'll set the thing off again or nothing. If it's nothing then don't reconnect, that'll just charge up the battery again. But then get the system looked at and, as Jim says, all the contacts tested. The sounder is only one small part of quite complex, constant-circuit-testing electronics.
If you get a replacement alarm fitted, ensure that it's a Europe-wide available system, with repairers/installers everywhere, and preferably NOT Italian made...

I think you may be onto something there Jim . The issues occur pretty much the same time every day after we have stopped for the night . So the engine has cooled down .. It may be the change in voltage that causes it to shriek . Once it’s stopped it doesn’t start again til the next day . Today it went on for a looonng time though . We are here til Monday so if my theory is correct then it may be OK. Forgive my ignorance but why would a sensor connector matter when the alarm is disabled ?

Too complex . And we are always upset to find standard issue on our bus is Italian !

Too complex . And we are always upset to find standard issue on our bus is Italian ! Alarms have voltage sensors, so that if an attempt is made to cut power to the alarm, or even alter the microvoltage running through all the sensors, it sets it off. So it may be a "power issue" with the vehicle battery/charging system. Also, from the fact that yours utters strangled sounds, we could infer that either a connector associated with it is not passing full current OR maybe the internal alarm battery is kerfukked. Perhaps mark the wires, cut them one at a time but be prepared to quickly reconnect them. If you cut one, it's less likely the alarm will go off when you cut the second one but... who knows? At least if it's disconnected and not making a noise you can relax until you get it properly repaired. Good luck with this.

Is it connected to the engine battery? What happens when you start the engine? If its a voltage drop alarm would it not stop sounding if there was suddenly charge to the battery? If it does then your batteries fucked.
Anything technical like this, just ask me.
No. Dont thank me.

I may be wrong about this, but I think very few vehicle alarms have built in batteries. I'd cut one wire to the horn/sounder and if that didn't work I could always reconnect it, bared ends of the wire twisted together and taped up. Cutting a wire (or two) is not a fix but it may silence it and won't do any harm if it doesn't work. Cut it where there's slack otherwise you won't be able to rejoin it if you need to. Belay that. I've found a web site that says web there is a backup battery. I'll read more. www.inktec-uk.co.uk/Insurance/mazda-car-insurance.htm

If you never use the alarm then the sensors info can be forgotten about. If you had switched the alarm on and there was a faulty sensor the alarm would sound.

What puzzles me is the strangled sound of the sounder, not sounding properly. Either the internal battery is knackered and it's on it's last legs, barely able to make a sound OR there's a bad connection somewhere and my guess is corrosion in the wiring within sounder itself. Possibly!

Thanks all . It hasn’t gone off again yet . Let’s hope it stays that way ! We have wrapped the offending sound box in dog towels ( dirty ones , dogs won’t suffer 🙂) cis when he put his hand over it to try to silence it you could hardly hear it . At least if it waits when we are out it won’t be too offensive !
